1. Buoy and Generator Interaction with Ocean Waves : Studies of a Wave Energy Conversion System
Sammanfattning : On March 13th, 2006, the Division of Electricity at Uppsala University deployed its first wave energy converter, L1, in the ocean southwest of Lysekil. L1 consisted of a buoy at the surface, connected through a line to a linear generator on the seabed. LÄS MER
2. Energy from Ocean Waves : Full Scale Experimental Verification of a Wave Energy Converter
Sammanfattning : A wave energy converter has been constructed and its function and operational characteristics have been thoroughly investigated and published. The wave energy converter was installed in March of 2006 approximately two kilometers off the Swedish west coast in the proximity of the town Lysekil. LÄS MER
3. Terrain navigation for underwater vehicles
Sammanfattning : In this thesis a terrain positioning method for underwater vehicles called the correlation method is presented. Using the method the vehicle can determine its absolute position with the help of a sonar and a map of the bottom topography. LÄS MER
4. Assessment of Experimental, Computational, and Combined EFD/CFD Methods for Ship Performance Prediction
Sammanfattning : In today’s highly competitive market, alongside increasingly stringent regulatory requirements, the precise prediction of ship performance has assumed paramount importance for both design verification and operational evaluations. This thesis addresses the need for a comprehensive assessment of Experimental Fluid Dynamics (EFD), Computational Fluid Dynamics (CFD), and their combination to enhance the accuracy of performance predictions.

5. On the Hydrodynamics of a Monohull Ship in Following and Stern Quartering Seas
Sammanfattning : The demand for high-speed ships has been increasing by the years and high speed monohull ships are in common use for a wide variety of applications from fast general purpose workboats, pilot boats and patrol crafts to large naval vessels and fast ferries. It has been noted that a large number of high-speed monohull ships suffer relatively high risk for seakeeping problems in following seas, such as surf riding, broaching-to and reduced manoeuvrability in following and quartering seas.
